Definitely. In fact Syngenta recommends an adjuvant (such as Stylet-Oil) be tank mixed with Agri-Mek® to improve performance. Stylet-Oil will enhance the uptake of Agri-Mek® into the leaf when tank mixed at a spray concentration of 0.25% (1 qt per 100 gallons of water in the tank). However, growers will need a 1% spray concentration of oil if mildew control is required.
